High-temperature and high-pressure dry sorbent autothermal desulfurization device

摘要

PURPOSE: A high pressure and high temperature dry desulfurization device is provided to perform natural desulfurization without an external heat source by supplying heat energy of a regeneration reactor to a desulfurization process. CONSTITUTION: A desulfurization reactor (10) supplies original gas to the bottom through an original gas supply pipe (28) and a solid desulfurization agent absorbs sulfur compounds. The solid desulfurization agent separating unit separates the solid desulfurization agent from mixture gas and exhausts residual gas. A regeneration reactor (20) discharges sulfur adsorbed by the solid desulfurization agent as sulfur dioxide by supplying regeneration gas to the solid desulfurization agent. A heat exchange jacket (22) connected with the original gas supply pipe is installed in the regeneration reactor. A driving heater (40) raising the temperature of the original gas to a desulfurization temperature is installed in the original gas supply pipe.
